To ensure maximum operational safety and flawless performance in petrochemical applications, we offer standard-compliant verification:
This valve body is presented as a representative custom‑manufactured component for Application and host equipment must be confirmed against the approved drawing before publication. Honyang Cast develops similar parts from customer drawings rather than offering a fixed catalog specification.
The manufacturing plan must connect the part's functional geometry—6 mm narrow flow channel; Complex inner cavity; Difficult‑to‑dry geometry—with tooling, investment casting, machining and measurable inspection requirements. Final dimensions, interfaces and acceptance criteria are confirmed during drawing review.
PROJECT‑SPECIFIC SUPPLY
Material grade, dimensions, tolerance zones, machining allowance, surface condition, operating requirements and inspection records are confirmed after review of the customer’s 2D drawing, 3D model and project specification.
The parameter set is selected for this component’s function. Unknown values remain drawing‑controlled and must not be replaced with generic catalog data.
| Engineering Item | Reference / Custom Requirement | Verification Basis |
|---|---|---|
| Material grade | Grade 316 Stainless Steel (CF8M / 1.4408) | Confirm governing standard and chemistry requirements. |
| Part weight | 9.86 kg | Confirm target weight and allowable variation when relevant. |
| Functional geometry | 6 mm narrow flow channel; Complex inner cavity; Difficult‑to‑dry geometry | Identify drawing datums and critical‑to‑function features. |
| Casting / process reference | Lost‑wax casting; Wax‑part splicing; Complex inner‑cavity shell making; Difficult‑to‑dry geometry control; ISO 8062 (GB/T6414) CT6 casting tolerance; Precision surface machining | Confirm which steps apply to the quoted production route. |
| Dimensions and tolerances | To be confirmed from customer drawing. | Define casting tolerance separately from machined dimensions and GD&T. |
| Operating conditions | To be specified by customer. | Provide medium, load, temperature, pressure, speed or hygiene requirements as applicable. |
| Recommended additional fields | Customer drawing/revision; Component function; Material grade; Unit weight; Channel geometry; Interfaces; Casting tolerance; Machining datums; Balance requirement if applicable; Inspection requirements | Complete before publishing numeric claims or quoting production. |
| Structural Feature | Why It Matters | Manufacturing Response |
|---|---|---|
| 6 mm narrow flow channel | This feature influences fit, flow, load transfer, manufacturability or downstream assembly. | Review core strategy, cavity access, local wall thickness and cleanliness verification for the internal or intersecting features. |
| Complex inner cavity | This feature influences fit, flow, load transfer, manufacturability or downstream assembly. | Define datums, sealing or mating interfaces, machining allowance and integrity checks for the pressure or structural boundary. |
| Difficult‑to‑dry geometry | This feature influences fit, flow, load transfer, manufacturability or downstream assembly. | Define datums, sealing or mating interfaces, machining allowance and integrity checks for the pressure or structural boundary. |

A project‑specific route is established after review of geometry, alloy, tolerance, volume and validation requirements.

PROCESS SCOPE
Investment casting and CNC machining are described as the core route. Heat treatment, coating, polishing, balancing, pressure testing, radiographic testing, PPAP or other special processes must be shown as project‑specific unless their scope is confirmed.
Honyang Cast supports drawing‑based development of valve body and related investment cast components from manufacturability review through sample approval and repeat production.
| Application Requirement | Manufacturing Value |
|---|---|
| Drawing‑defined fit and function | A part‑specific DFM and inspection plan links casting geometry to the actual assembly and operating requirement. |
| Integrated complex geometry | Investment casting can consolidate features and reduce fabrication or excessive stock removal where the approved design supports it. |
| Repeatable critical interfaces | Controlled datums, machining and inspection support consistent assembly of functional surfaces and mating features. |
| Material and process traceability | Agreed material and inspection records provide evidence against the drawing and quality plan. |
| Product‑specific value | After identity confirmation, use as a manufacturability case for difficult‑to‑shell, narrow‑channel stainless investment castings. |
